flow-capture simply receives NetFlow data and stores it to disk.
You'll need to use that in combination with softflowd to listen for
raw packets on the NIC and generate the NetFlow information.

I highly suggest the book "Network Flow Analysis" by Michael Lucas if
you want to pursue this route; it's especially worth it if you're
going to leave this system around for long-term analysis.
